That’s what I was wondering, and I also think you’re right with the chassis not being accurate right out of the box.
They almost look like a good kart, but unfortunately the chassis is not designed to twist and flex like the Top Quality brand names.
Sorry, James, not trying to sound negative, but you may be fighting something that could be a bit frustrating
You could try to fix it and make it drivable and fun, who knows? it may be a good handling kart after all, but know that it may not last, and TJ is right, it was designed to be affordable for a low budget and an entry level chassis.
